A few things here. To go from 55 Strength (which is the default for the Interior Rusher archetype) to 80, you would need to spend 80 TPE. You start with 50 TPE total. Not including your increases in Intelligence, Agility and so forth. I notice you tried to compensate by subtracting from some stats but in the builds we are giving you base starting stats to add upon. So you'll need to take this build below and add 50 TPE to it again using the Update Scale, also listed below. BTW, I love the name. Hope you enjoy the league. Hit up this thread again with a response. If you need any help feel free to ask as well.
